Hi,
There is an nvme device but for some reason it is not being listed by pySmart.
python ouptut:
>>> import pySMART
>>> z=pySMART.DeviceList()
>>> z
<DeviceList contents:

smartctl:

Are you running that python with sudo/root?
Everything in the output seems to be OK, so that's the only thing that comes to my mind
Ok, wait, I think I've found something...
Ok, bug confirmed
hi @ulmitov
There was an issue checking nvme sizes, please, check the master/develop branches and confirm it is fixed.
Thanks for your contribution!
